-
- The following utility functions are available
-
- =over 4
-
- =item void GLwBeginProjection (Widget w)
-
- =item void GLwEndProjection (void)
-
- The following code snippet selects perspective projection for the
- workstation I<ws>:
-
- GLwBeginProjection (ws);
- glFrustum (-1.0, 1.0, -1.0, 1.0, 1.0, 10.0);
- GLwEndProjection ();
-
- During redisplay, this will be executed as a display list with the
- matrix mode set to I<GL_PROJECTION> and an identity matrix on top of
- the projection matrix stack.
-
- =item void GLwPostProjectionList (Widget w, GLuint p)
-
- =item void GLwPostProjectionMatrix (Widget w, GLdouble *m)
-
- =item void GLwPostCurrentProjection (Widget w)
-
- =item void GLwUnpostProjection (Widget w)
-
- =item GLuint GLwGetProjectionList (Widget w)
-
- =item int GLwGetProjectionMatrix (Widget w, GLdouble *m)
-
- =item void GLwSetFrustumProjection (Widget w, GLdouble left, GLdouble right,
- GLdouble bottom, GLdouble top, GLdouble near, GLdouble far)
-
- =item void GLwSetOrthoProjection (Widget w, GLdouble left, GLdouble right,
- GLdouble bottom, GLdouble top, GLdouble near, GLdouble far)
-
- =item void GLwBeginView (Widget w)
-
- =item void GLwEndView (void)
-
- The following code snippet selects a view from the z-axis for the
- workstation I<ws>:
-
- GLwBeginView (ws);
- gluLookAt (0.0, 0.0, 3.0,
- 0.0, 0.0, 0.0,
- 0.0, 1.0, 0.0);
- GLwEndView ();
-
- During redisplay, this will be executed as a display list with the
- matrix mode set to I<GL_MODELVIEW> and an identity matrix on top of
- the model view matrix stack.
-
- =item void GLwPostViewList (Widget w, GLuint v)
-
- =item void GLwPostViewMatrix (Widget w, GLdouble *m)
-
- =item void GLwPostCurrentView (Widget w)
-
- =item void GLwUnpostView (Widget w)
-
- =item GLuint GLwGetViewList (Widget w)
-
- =item int GLwGetViewMatrix (Widget w, GLdouble *m)
-
- =item void GLwSetPolarView (Widget w, GLdouble r, GLdouble theta, GLdouble phi)
-
- =item void GLwPostObject (Widget w, GLuint o)
-
- posts I<object> to I<w>.
-
- =item void GLwUnpostObject (Widget w, GLuint o)
-
- =item void GLwUnpostAllObjects (Widget w)
-
- =item void GLwRedrawObjects (Widget w)
-
- force a redraw of all objects posted to I<w>.
